Ssas MDX-创建动态分组成员？

类别{A，B，C}

价值观

目前我可以获得：

Category    Value
--------    -----
A           100
B           200
C           300

我想得到的是：

Category    Value
--------    -----
A           100
B           200
C           300
D           500

Category    Value
--------    -----
A           100
B           200
C           300
D           500

其中D是B+C的值。

哇，这实际上非常简单

with member [Category].[Name].[D] as
    [Category].[Name].[B] + [Category].[Name].[C]

select
    {[Measures].[Value]} on columns,
    [Category].[Name].allmembers on rows
from [Cube]

结果:

哇，这真是太容易了

with member [Category].[Name].[D] as
    [Category].[Name].[B] + [Category].[Name].[C]

select
    {[Measures].[Value]} on columns,
    [Category].[Name].allmembers on rows
from [Cube]

结果:
